I mentioned in a previous post that, this year, QRM levels here at the condo in Québec are higher on our balcony than they are inside the building.
I think I found the source.
A couple weeks ago, on my morning walk, I passed underneath some high voltage power lines about 1 km from the condo. I noticed the sound of arcing coming from a pole nearby. No doubt, something metal–a staple, a cable, a pin, etc.–is the culprit.
I pulled out my smart phone and made this short video. If you turn up the volume, you might hear the noise especially at the end of the clip.:
I took a portable radio back to the site later and heard the same broadband noise I heard from the condo.
Although we only rent this condo a couple months a year, I’ll try to report the noise to the Hydro Québec. I know that our utility company in the States must follow up with requests like this and do their best to eliminate unintentional sources of RFI. These issues can also be an indication of something in the system failing, so power companies can actually be quite grateful for the feedback.
If you have persistent broadband noise at home, check out some of the trouble shooting tutorials at K3RFI’s website for a little guidance.
No worries, though, I’ll be back at my home station soon and can once again enjoy a relatively RFI-free radio space!
